invention relates to a new andusef ul improvement in a self reversing slicing machine, adapted for slicing articlessuch as vegetables, fruits. andt-he like, and has, for its-object ithefprovision of a machine ofthis classin which the material to be sliced may be reciprocated over the machine and broughtinto contact with. cutting blades when travelling in either direction, so that a maximum efliciency oi the machine is e f-.

fected, .in that the cutting is done in both directions. j ,iinother object isthe provision of; a mech- I '-'anis1nwhereby the cutting blades are auto matically reversed upon the travelfof the material to either-side sothat thejblade is adapted for cutting the material travelling in one direction dependent upon the direc-j V I V P-On which isfixedly niountied theeblade'31 75 tionof travel: of the material. 20 Another object of the invention is. thepro vision .ofan adjustingwmechanism whereby the s'ize.of-the cut may bei'regulated, :Other objects will, appear'hereinafter.-

The invention consists in the combination and, arrangement 0t parts hereinafter described and claimed. r j v The invention 'willbebest understood by a'reference to theaccomp'anyi'ng drawings, which form a part of this specification and in which, 1 I i Fig. 1 is a top plan viewv of; the invention.

"The inventioncomprises a bed? having. side walls 9 and 10 which project above and below the bed 7, the downwardly projecting, portion serving as a support for the bed 7. and the upwardly projecting sides .9 and 10 being each provided with longitudinally err-- tending grooves 9 and 10". respectively, in which engage ribs 131 and 14 respectively whichfprojectout ironi the side walls 15 and 16 respectively ofa 'mate'rialcontainer, having the" end ivallsll'and 18. A suitable cover 19 iseprovided for the container, this cover also serving as a follower for the ma-' terial so as to press it firmly against the bed 7 7. A convex bottom 20 is formed on the cover so that the follower will ride over the cutting elements when travelling in either direction. Secured to the bed 7 and the downwardly projecting portions of the side walls 9 and l0 are guide brackets 21vwhich' slidably support a bar 22, projecting upwardly from whichat. one-.endiis an arm 23 extending through a slot. 24 1formed in the 160 bed Asimilar arm 25 projects upwardly from the opposite end of the bar 22 and e atends through a slot 26Qformed in thebed 7, These armsareextendtzdso as to project above the upper surface of the b'e'd/7 and V engage the walls 17 and 18 upon movement of the material container, which-may be termed. a carriage; to either. sideofthe-bed 7.

. In this way I have provided a device whereby the 'blades automatically reverse themselves for slicing the material depending upon the direction of travel of the ma-, terial. I have also provided an adjustment means for regulating the tilt of the knives and thus adjusting the thickness of the slices projecting through a slot formed therein; a

or depth of the cut. U

It is believed that the simplicity and durability of the structure will be recognized from the description given and that it is one which may be economically manufactured and quickly assembled. I

lVhile I have illustrated and described the preferred form of my invention I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as opposite ends of said bed; means for connecting sa1d engagement members; and

means on-said connecting means for engaging said arm and rocking said cutting element on its, mountings upon movement of either of said engagement members in either direction.

'2. A cutting machine of the class described comprising: a bed; a cutting element rockingly mounted on said bed in an opening formed therein and adapted upon rocking in either direction for extending one of its edges above the surface of said bed;-

an engagement member at each side of said bed projecting through a slot formed therein; a bar positioned below said bed and connecting said engagement members, said engagement members and said bar being longitudinally slidable relatively to said bed;

an arm projecting downwardly from said cutting element; and means on said bar for engaging said arm upon slidable movement of said bar in either direction for locking said cutting element to project its edges above the surface of said bed. h i

3. A cutting machine of the class described comprising: a bed; a cutting element rockingly mounted on said bed in an opening formedtherein and adapted upon rocking in either direction forextending one of its edges above the surface of said bed; an engagement member at each side of said bed barpositioned below said bed and connecting said engagement members, said engagement members and said bar being longitudinally slidable relatively to said bed; an arm projecting (lOWDW-iLIClly from said cutting element; and means on said bar for engaging said arm upon slidable movement of said bar in either direction for lockingsaid" cutting element to project its edges above the surface of said bed, said engagement members connected by said bar being in the position of travel of an article sliced when slid over said bed.-

LA cutting machine of the class described, comprising: a bed; a cutting element rockably mounted in an opening formed in said bed; an engagement member at each end ofsaid bed projecting through a slot formed 1n sa1d bed; means below said bed for connecting said engagement members, sa1d engagement members being slidable in unison longitudinally of said bed and in the path of travel of an article slid over sa1d bed, the engagement of said article with said engagement members effecting a longitudinal movement of sa1d bar; and means on sa1d bar for, upon longitudinal movement of the same, rocking said cutting element to brin its opposite edges above the upper surface of said bed. l

5. A cutting machine of the class described, comprising: a bed; a cutting element rockably mounted in an opening formed in said bed; an engagement member at each end of said bed projecting through a slot formed in said bed; means below said bed for connecting said engagement members, said engagement members being slidable in. unison longitudinally of said bed and in the path-of travel of an article slid over said bed, the engagement of said article with said engagement members effecting longitudinal movement of said bar; means on said bar for, upon longitudinal movement of the same, rocking said cuttingelement to bring its opposite edges above the upper sur= face of said bed, the degree of movement of said bar determining the pitch of said cutting element relatively to said bed; and

In testimony whereof I have signed the foregoing specification.
